INKING APPARATUS FOR PRINTING-MACHINES.

Specification of Letters Patent.

Patented Aug. 2, 1910.

To all whom it may concern:

Be it known that I, SAMUEL HOLLINGS- WORTH, a citizen of the UnitedStates, re-

siding at Plainfield, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in Inking Apparatusfor Printing-Machines, of which the following is a specification.

This invention relates to improvements in the mechanism for -operatingthe fountain and ductor rolls of an inking apparatus; and my object isto provide means for operating said rolls by means of thereciprocations'of the ink, distributing, or vibrator, roll; and,further, to provide means for adjusting the degree of partial rotationto be imparted to the fountain roll for each oscillation of the ductorroll. a

I attain my objects by constructing the apparatus in the mannerillustrated in the accompanying drawings, in which- Figure 1 representsa plan view of an inking apparatus embodying my improvements, withportions thereof cut away; Fig. 2, a side elevation thereof with theside frames removed; Fi 3, a detail in section, illustrating the a justing device for the fountain roll mechanism; Fig. 4, a plan view of aportion of Fig. 3; Fig. 5, a sectional detail on the line a2zv in Figs.3 and 4; and Figs. 6, 7, and 8, details illustrating the severalpositions assumed by the operating levers for the ductor and fountainrolls during the reciprocations of the vibrator roll.

Like numerals designate like parts ,in the several views.

Mounted between the side-frames 1, 1, are the plate cylinder 2, the inkdistributing, or vibrator,roll 3, and the composition inking rolls 4, 4,all arranged in the usual man- -ner, and driven from the main gear trainof the printing machine by means of the gears-5, 6; 7, and 8. Thevibrator roll is carried by the shaft 9, which is adapted to bereciprocated in its bearings, in the usual manner, by means of thegrooved collar 10, fastened to one end thereof and engaged by a rollercarried on the bell crank lever 11.

nec'ting rod 12, coupled to an operating -crank, or the like, (notshown), which is driven from the maln gear train at some suitable pointon the machine.

The inking fountain, 13, is supported at the end of the side-frames, andis to be constructed in the usual manner. The fountain roll, 14, is alsoof the usual construction, and arranged in the usual manner with respectto the ink fountain.

The ductor roll 15, which carries the ink from the fountain roll to the.vibrator, is formed upon a shaft, the ends of which are loosely mountedin bearings in the upper ends of the rock, arms 16, fastened to theshaft 17, which is journaled in the sideframes below the ductor roll.Fastened to this shaft 17 is a lever 18,. provided at its free end witha roller 19, having a portion of its peripheral surface of conical form.This roller is positioned to ride upon the conical cam 20 on thevibrator roll, as said roll reciprocates. The cam 20 lies between twocylindrical surfaces 21 and 22 of such diameters, respectively, that,when the roller 19 rests upon the surface 21, the ductor roll willengage the vibrator; and, when the roller rests upon the surface 22, theductor roll will be thrown over into engagement with the fountain roll.The lever 18, and its roller 19, will be held in engagement with thevibrator cam by means of a suitably located spring, not shown.

The fountain roll, at one end, is provided with a ratchet wheel 23,engaged by pawl 24 mounted upon the lever 25, said lever being actuatedin turnby means of a second lever 26, loosely mounted upon the shaft 17,the two levers being provided at 27 with intermeshing gear segments, asshown more clearly in Fig. 2. lever 26 is provided with a roller 28,having one portion, of its surface coned to correspond with the cam 20,said roller engaging and being actuated by the cam 20, in the samemanner as described in connection with roller 19; and it will be evidentthat, as the roller 18 rides up on the cam, pawl 24 will be actuated tomove the ratchet wheel one or more teeth, according to how far up thecam the roller 28 is permitted to go.

In order to adjust the throw of the lever 26, so as to impart a greateror less degree of rotation to the fountain roll, and thereby regulatethe feed of the ink to the ductor roll, I provide means for shifting thelever 26 upon the shaft 17, so as to. give the roller 28 a lateraladjustment relative to the cam- The free end of the more or less at eachreciprocation of the vibrator roll. This adjusting device comprises akey 29, which asses through a slot 31 cut through the shaft 17, the endsof said key passing also throu h transverse slots 30, formed in the hub0 the lever 26. The slots 30 are of suflicient width to permit of therelative motions of the shaft 17 and the lever 26 when actuated by therollers 19 and 28 respectively, .as the ride up and down the cam. Thekey 29 isnotched at the center and engaged by the end of an adjustingscrew 32, which passes out through the end of the shaft, and is providedwith a suitable turnin knob. The key is held against the end 0 theadjusting screw, and moved in the opposite direction, by means of acoiled spring 33, as shown in Fig. 3. By means of this sliding key, thelever 26 may be adjusted laterally in either direction, so as to causethe roller 28 to approach or recede from the cam, thereby increasing ordiminishing the throw of the lever 25 and the pawl 24, so that thelatter will be drawn back a greater or less number of teeth on theratchet .wheel to impart a greater or less degree of rotation to thefountain roll. By means of this arrangement, the ductor roll may begiven a longer period of contact with the vibrator roll and with thefountain roll, than is customary in this type of inking apparatus, by soarranging the length of the reciprocations of the vibrator roll that theroller 19, after riding up or down the cam 20, may ride for a greater orless period upon the cylindrical surfaces 21 and 22; and this period ofcontact may be further increased or diminished by varying the speed ofthe reciprocations relatively to the number of rotations of'the vibratorroll; this latter adjustment being accomplished, in any suitable manner,through the operating mechanism for the crank lever 11. It will also benoted that the fountain roll will have motion imparted to it while theductor roll is being held in contact therewith, thus efi'ectivelydelivering the ink to a greater or less extent of surface on the ductorroll according to the adjustment of the ratchet mechanism.

The relative movements of the levers l8 and 26, and their rollers 19 and28, respectively, will be understood from an inspec- What I claim as myinvention and desire to secure by Letters Patent is 1. The combination,with vibrator, ductor and fountain rolls, of means actuated by thereciprocations of the vibrator roll for imparting motion to the ductorand fountain rolls.

2. The combination, with vibrator, ductor and fountain rolls, of a shaftprovided with rock arms in which the ductor roll is mounted to oscillatebetween the vibrator and fountain rolls, and means actuated by thereciprocationsof the vibrator roll for oscillating said shaft.

3. The combination, with vibrator and fountain rolls, of a ratchetmechanism for turning the fountain roll, and means actuated by thereciprocations of the vibrator roll for imparting motion to said ratchetmechanism.

4. The combination, with vibrator and fountain rolls, of a conical. camon the vibrator roll, a shaft provided with rock arms, a ductor rolljournaled in said arms, and alever fastened on said shaft, said leverbeing engaged by the cam, as the vibrator reciprocates, to oscillate theshaft.

5. The combination, with vibrator and fountain rolls, of a conical camon the vibrator roll,,a ratchet mechanism for turning the fountain roll,an oscillating lever engaged by said cam as the vibrator reciprocatesand adapted to impart motion to the ratchet mechanism, and means foradjusting said lever to increase or diminish its distance of travel uponsaid cam.

6. The combination, with vibrator, ductor and fountain rolls, of aconical cam on the vibrator roll having cylindrical surfaces ofdifi'erent diameters'at the sides thereof, a shaft between the vibratorand fountain rolls provided with rock arms in which the ductor roll isjournaled, a lever fastened upon said shaft and having itsfree endadapted to ride upon said cam and cylindrical surfaces as the vibratorreciprocates, a ratchet mechanism for turning the fountain roll, a leveradapted to impart motion to the ratchet mechanism loosely mounted uponthe shaft and having its free end also adapted to ride upon said cam andcylindrical surfaces, and means for adjusting said lever longitudinallyupon the. shaft.

In testimony whereof I have aflixed my signature, in presence of twowitnesses.
